Our Core Services

Cost Segregation Studies (IRC §§167 & 168)

We perform engineering-based cost segregation analyses that identify and reclassify eligible property components into accelerated recovery periods while maintaining audit defensibility. 100% Bonus Depreciation permanently restored on qualified property placed in service after January 19, 2025, so long as the binding contract to acquire the property was signed on or after that same date.

Our approach emphasizes:

• MACRS-compliant classification (5-, 7-, 15-, 27.5 and 39-year property)

• Proper separation of land, land improvements, and building components

• Application of relevant case law (e.g., Hospital Corporation of America)

• Conservative benefit modeling and explicit risk disclosure

Best suited for:

Commercial and industrial properties with meaningful depreciable basis and long-term ownership intent.

R&D Tax Credits (IRC §41)

We identify and document qualifying research activities and expenses under IRC §41 using a strict application of the Four-Part Test.

Our methodology includes:

• Pass/fail eligibility analysis for each test element

• Clear distinction between qualifying and non-qualifying activities

• Conservative identification of Qualified Research Expenses (QREs)

• Audit-ready technical narratives tied directly to claimed costs

Best suited for:

Companies developing, improving, or scaling products, processes, software, or manufacturing techniques.

Land Nutrient Deductions (§180)

We assist agricultural and land-owning businesses in identifying deductible soil and land preparation costs under IRC §180.

Our analysis focuses on:

• Proper classification of qualifying expenditures

• Clear separation from capital improvements

• Supportable documentation tied to agronomic purpose

• Conservative application aligned with IRS expectations

Best suited for:

Farming operations, land developers, and agricultural businesses with material soil preparation costs.

(A great benefit to go along with this deduction, is a possible Cost Segregation study. The strategies are complementary and may both apply when agricultural properties include substantial building improvements.)
